OVERVIEW

High-Performance Zirconia Grinding

The Pferd POLIFAN® PSF ZIRKON-EXTRA Flap Disc (SKU: 60632) represents a significant advancement in abrasive technology for industrial metalworking. Engineered for professionals who demand efficiency and longevity, this 5-inch disc utilizes premium Zirconia Alumina grain, known for its toughness and self-sharpening properties. The 36 grit configuration is specifically designed for coarse grinding tasks, making it an ideal choice for heavy stock removal, weld leveling, and edge chamfering on carbon steel and stainless steel substrates.

Extended Service Life

What sets the ZIRKON-EXTRA line apart is its high-density construction. These discs are built with approximately 40% more abrasive material compared to standard PSF flap discs. This "Extra" density translates directly to extended service life, allowing operators to work longer without stopping to replace consumables. The unique flap arrangement not only packs more material onto the backing but also provides a consistent finish throughout the life of the disc.

Optimized Geometry

This disc features a Type 29 conical profile. Unlike flat (Type 27) discs, the Type 29 shape is angled to provide maximum surface contact when the grinder is held at a natural 15 to 25-degree angle. This geometry enhances the aggressiveness of the cut and improves user comfort by offering a slightly cushioned grinding effect, reducing vibration and operator fatigue during prolonged use. The 7/8-inch arbor ensures compatibility with a wide range of standard industrial angle grinders.

Applications

  • Heavy weld seam removal
  • Chamfering and edge breaking
  • Surface grinding on steel and stainless steel
  • Deburring flame-cut parts

FAQ

Type 27 discs are flat and best for blending and finishing on flat surfaces. Type 29 discs, like this one, are conical (angled) and are better suited for aggressive stock removal and contour work.

While Zirconia can grind aluminum, it is not optimized for it and may load up (clog) quickly. It is best suited for steel and stainless steel. For aluminum, look for discs specifically designed with coatings to prevent loading.

The 'Zirkon' refers to the Zirconia Alumina abrasive grain. 'Extra' indicates that the disc is constructed with approximately 40% more material than standard discs, providing a longer service life.

This disc has a standard 7/8-inch arbor, which fits most 4.5-inch and 5-inch angle grinders.

No, 36 grit is a coarse abrasive designed for heavy stock removal and grinding. For finishing or blending, you would typically step up to a 60, 80, or 120 grit disc.

These are typically sold individually or in packs of 10. Please check the specific quantity selector on the product page.

Always check the label on the actual disc for the safety rating, but standard 5-inch flap discs are typically rated for around 12,200 to 13,300 RPM.

No, flap discs have a built-in backing plate (usually fiberglass or plastic) and do not require a separate backing pad like fiber discs do.
